Genesis G90, RS4 (USA)

Brake fluid capacity & service interval

Genesis G90 and RS4 (USA) models utilize brake fluid with a capacity range between min and max. Service intervals occur at 48000 miles or 48 months. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications

Additional Notes

  • All three G90 configurations covered here share identical brake fluid service intervals, set at 48,000 miles or 48 months, whichever comes first under normal use conditions.
  • The Genesis G90 3.5 T-GDI specifies brake fluid fill to a level between the reservoir minimum and maximum marks rather than a fixed volume, which is standard practice for hydraulic brake system top-ups during routine service.
  • The AWD variant carries the same 48,000-mile or 48-month change interval as the rear-wheel-drive model, indicating no differentiation in brake fluid service requirements between the two drivetrain configurations.
  • The G90 3.5 T-GDI AWD MHEV, which incorporates a mild hybrid electric system, follows the same hydraulic brake system fluid interval of 48,000 miles or 48 months as the non-hybrid variants, reflecting a conventional hydraulic brake circuit rather than a fully regenerative one.
  • A "between min and max" fill specification means the reservoir level is the reference point for service, so no discrete fluid capacity figure in quarts or liters is assigned to a brake fluid change on any of the three G90 configurations listed.
